LibreSignage v1.1.0 release

After a lot of development LibreSignage v1.1.0 is finally
here. This release includes a ton of new features as well as
bug fixes and more. Users of LibreSignage v1.0.x are encouraged
to upgrade as soon as possible.

This release includes support for automatically migrating data
created by older versions of LibreSignage so the upgrade process
should be quite easy. There's no manual work needed; data is
migrated automatically when the web interface is accessed.

Some major changes:
  - A rewrite of the server-side API system.
  - Major backend code improvements.
  - Support for HTTP caching slides resources.
  - A data migration system for simplifying upgrades
    between LibreSignage versions.

Docker images for this release will appear in the LibreSignage
Docker Hub repository as "eerotal/libresignage:v1.1.0" and
"eerotal/libresignage:latest". You can also build this release
from source by following the instructions provided in the readme.
Note that the build system has changed a bit from previous versions,
so you should probably give the instructions a read even if you
have built previous versions yourself.

Changelog v1.1.0:
  - [internal] Separate private and public files in the directory tree
               to naturally prevent access to private files. (PR #56)

               slide backgrounds. (issue #75)
  - [feature]  Implement buttons for manual slide navigation in display.
  - [internal] Mostly rewrite the API system
  - [internal] Use PHP autoloading and namespaces instead of direct
               file includes.
  - [internal] Improve various classes and PHP files to make them more object
               oriented.
  - [internal] Implement a testing framework with PHPUnit and write tests
               for all API endpoints.
  - [bugfix]   Fix various bugs in the backend that were discovered while
               writing tests.

               when the slide was not locked. (issue #81)
  - [bugfix]   Fix a bug where a slide could be deleted even when it was
               not locked. (issue #80)
  - [bugfix]   Fix a bug where an error was thrown when changing queues if an
               unsaved slide was open. (#86)

LibreSignage v1.1.0-beta-1 release

This is the first beta release for LibreSignage v1.1.0. The full
changelog is included below.

This release includes a rewrite of the server-side API system and major

quite a bit.

You can begin testing this release by either building from source or by
using the prebuilt Docker images from Docker Hub. The readme has

LibreSignage v0.2.0

This is the first non-beta release of LibreSignage. This release
contains a huge amount of changes, improvements and new features.
There have been ~180 commits since the last release. The changelog
is included below and it can also be found in the file changelog.txt
in the source root.

Changelog:

v0.2.0
  - [feature]  Implement keyboard shortcuts for the editor.
  - [feature]  Make it possible to preserve instance data when
               reinstalling.
  - [feature]  Implement a live slide preview in the editor.
  - [internal] Self host font files. (I actually don't particularly
               like including binary files in the GIT tree but I don't
               know of a better way so the font files are now included
               in the tree.)
  - [internal] Use SCSS instead of plain CSS for the stylesheets.
  - [internal] Import Bootstrap straight into the _default.scss file
               instead of including it in the HTML <head> tag.
  - [internal] Process CSS using PostCSS /w Autoprefixer.
  - [bugfix]   Fix a major security issue where the contents of the
               'data/' directory were accessible by requesting the
               different files with eg. a web browser. Even directory
               listings were enabled.
  - [feature]  Completely rewrite the markup transpiler system to
               improve its error detecting and reporting capabilities.
               The rewrite also introduced many other improvements. The
               transpiler now uses the familiar lexer-parser-evaluator
               architecture that most compilers use.
  - [feature]  Improve markup error reporting in the editor UI. Erroneous
               code lines are now highlighted in the editor input.
  - [bugfix]   Confirm before changing the queue if an unsaved slide
               is being edited in the editor (#17).
  - [bugfix]   Prevent creating duplicate queues in the editor.
  - [bugfix]   Don't show unstyled slide previews to users in the editor
               by making sure the necessary CSS is loaded before showing
               content.
  - [bugfix]   Fix a bug resulting in spurious slide changes on the
               display page.
  - [improve]  Make the login and user manager pages more mobile friendly.
  - [feature]  Implement a Quick Help view in the editor.
  - [Internal] Implement a new way of exporting PHP object data by using
               a class called Exportable.
  - [feature]  Implement slide locking to prevent simultaneous editing
               of slides (issue #18).
  - [internal] Rewrite most of the PHP session handling code. Implement
               a new class called Session for handling & storing session
               data.
  - [internal] Implement a simple assertion system in JavaScript.
  - [internal] Implement file uploading via the API system.
  - [feature]  Implement media storage & uploading in the backend and
               editor.
  - [feature]  Implement embedding video in slides using [video] tags.

LibreSignage v0.1.1-beta patch release

This release fixes a few major issues in the v0.1.0-beta release.

Shortlog:

eerotal (3):
      api: Fix session renewal not working (#15)
      api: Completely fix session renewals not working (#15)
      config: Prevent web access to 'data/' and disable directory
      indexing

LibreSignage v0.1.0-beta

This is the first beta release of LibreSignage. Since releasing the
first alpha version, a massive amount of things have changed and
a lot of of new features have been implemented. In fact, the changelog
for this release would be so big that I'm not even going to write one.
If you want to see what has changed, you can read the commit history
instead.

LibreSignage has matured quite a bit since the first alpha release and
I'd even consider it mostly usable in real world scenarios by now.
However, many new features and changes are planned, so things will
probably still change quite a bit in the future.

LibreSignage v0.1.0-alpha release

First alpha release of LibreSignage. All basic functionality is
implemented and LibreSignage is starting to be usable. Some bugs
and other problems probably still exist and a lot of planned
features are not yet implemented.
